IMPROVEMENT IN WOOD PAVEMENTS.

Specification forming part of Letters Patent N 0. 118,528, dated August29, 1871.

To all whom it may concern:

Be it known that I, J AMIES F. GYLES, of Ohicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement in\Vooden Pavements; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawing making a part of this specification, in whichFigure 1 is a plan view of my pavement. Fig. 2 is a transverse sectionalelevation, and Fig. 3 a longitudinal sectional elevation.

This invention has for its object to provide a cheap pavement, soconstructed as to allow of perfect drainage transversely or laterallyfrom its ridge; one also less liable to premature decay, and whoseblocks shall be invertible and more easily removable than thosepavements as ordinarily constructed. The in vention relates to apavement whose foundation consists of boards or planks laid at intervalsof an inch, more or less, crosswise of the street instead of lengthwise,as heretofore, upon the ordinary sand-bed, and whose rows of blocks arealso laid crosswise of the street upon the board foundation and directlyabove the intervals thereof, each row of blocks being furnished with alongitudinal rib running centrally of one side, and armed withprojecting nails which extend into the ribless side of the next row ofblocks when the latter are driven up against the aforesaid rib, by whichconstruction there are created two longitudinal spaces between every twoadjacent rows of blocks, of which spaces the upper is to be filled witha novel concrete of my own invention and the lower is to be left openfor drainage into the gutters at the sides of the streets.

Referring to the drawing, a is the sand-bed, the same being graded to acrown at the center. I) are the foundation planks, each one and onehalfor two inches thick and six or eight inches wide, and resting at theirends on stringers running lengthwise. 0 are the intervals between theplanks I), each one-half or one inch wide. f are the blocks. g arethe'ribs, composed either of separate pieces secured one to each block,or

one to several blocks, or of one piece secured to a whole row. Theseribs are either nailed to the sides of the block, or inserted in groovescut in the sides of the blocks, or formed in one piece \vith each block,or secured to the blocks in any other sufficient manner. h are the nailsprojecting from the ribs. 2' are the drainage spaces between the rowsbelow the ribs; and j the upper spaces, filled with concrete underhydraulic pressure.- j are the usual inclined planks placed lengthwiseof the street at each side of the foundation, with their upper edgeselevated, forming the foundation of the gutter-blocks k, between whichand the blocks f are the triangular gutters 70, into which the drainsz'open .at each end.

In case the ribs g are composed of separate pieces, the nails h shouldbe driven through them before they are attached to the blocks. By placing the foundation planks crosswise of the street, and at intervals,the same draining facilities are secured for them through the spaces 0as for the blocks.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a wooden pavement, the combination of two or more rows of blocks,f, ribs g, and nails or spikes, as specified, and a cement applied tofill the space formed between said blocks and above the ribs, thecorresponding space below the ribs being left open, as herein shown anddescribed, for the purpose set forth.

2. An improved wooden pavement formed by I the combination of thefollowing elements, viz., V

rectangular blocks f, ribs 9 attached to said blanks by nails or spikes,a cement applied to fill the space above the ribs, and strips or planksb laid transversely of the street with spaces between them, and eachforming a support for one side or edge of a row of blocks, all arrangedas shown and described.
